2021-05-24drm/vc4: Separate VEC compatible variantsMateusz Kwiatkowski1-5/+22
The VEC's DAC on BCM2711 is slightly different compared to the one on BCM283x and needs different configuration. In particular, bit 3 (mask 0x8) switches the BCM2711 DAC input to "self-test input data", which makes the output unusable. Separating two compatible variants in devicetrees and the DRM driver was therefore necessary. The configurations used for both variants have been borrowed from Raspberry Pi (model 3B for BCM283x, 4B for BCM2711) firmware defaults.

When devm_ioremap_resource() fails, a clear enough error message will be printed by its subfunction __devm_ioremap_resource().

2021-05-20vgaarb: Use ACPI HID name to find integrated GPUKai-Heng Feng1-5/+26
Commit 3d42f1ddc47a ("vgaarb: Keep adding VGA device in queue") assumes the first device is an integrated GPU. However, on AMD platforms an integrated GPU can have higher PCI device number than a discrete GPU. Integrated GPU on ACPI platform generally has _DOD and _DOS method, so use that as predicate to find integrated GPU. If the new strategy doesn't work, fallback to use the first device as boot VGA.
